For cleaning of smartphones, it seems, however, to be very useful - at least if you can get stuck nowhere. For this, I have not but bought myself.
Conclusion: Not recommended. Joy quality (motto of ALCLEAR) is unfortunately only beindgt. And I thought to myself that this particular cloth should suck what I am absolutely satisfied with the Autopflegeset (sponge, gloves, large dry cloth) of ALCLEAR. The price of 3.75 is better described as a high-priced for such a small cloth. It remained only to return what but at the price hardly worthwhile.
Supplement dated 05/28/12:
Today I had an email from ALCLEAR in the mailbox that you sends me free as a goodwill gesture in the cloth 19x14 cm as I have reported on the booze education. This customer service I find very good. I hope that this cloth because of the size works better. But I would wish me also that reviews such, contribute to an improvement of my products.
